Reclaim your turf from tough weeds with Manuscript

By Lane Tredway, technical services manager, Syngenta

Controlling grassy weeds is a difficult task, especially if pre-emergent herbicides either were not applied or failed to provide acceptable control for any reason. Very few options are available for post-emergent control of grassy weeds in bermudagrass and zoyisagrass turf, especially in lawns where monosodium methanearsonate (MSMA) use is prohibited. Without viable options for control, many turf areas have been taken over by tropical signalgrass, crabgrasses, dallisgrass and other weeds.

Looking to control grassy weeds in cool season turf? Consider Fusilade® II herbicide
Manuscript® herbicide presents a powerful option for control of tropical signalgrass, crabgrasses, dallisgrass and certain other weeds in bermudagrass and zoysiagrass turf. The active ingredient, pinoxaden, works through the ACCase mode of action, but has a unique safety profile and control spectrum thanks to its unique phenylpyrazoline chemistry. The Manuscript formulation also includes a safener, cloquintocet-mexyl, to further enhance turf safety. Because of its outstanding turf safety, Manuscript makes an excellent option even in areas where MSMA is available. It is packaged with Adigor™ surfactant, which was specifically designed to maximize Manuscript absorption and translocation in target weeds.

Two spot-treatment applications of Manuscript at 9.6 fl. oz. per 10,000 ft.2 on a 14- to 21-day interval provide consistent control of mature weeds — even in summer when other chemistries often struggle. Because Manuscript provides effective control in summer, when turf is growing most aggressively, turf managers can use fertility and cultural practices to encourage re-growth into the voids where weeds were established.

For best results, Manuscript should be applied in 40 gallons of water per acre with a 0.5% concentration of Adigor. Target weeds should be actively growing, i.e. not under stress from drought or other factors, to maximize absorption and translocation of the active ingredient.

When controlling tropical signalgrass or crabgrass, sedges and broadleaf weeds can often move in very quickly and compete against the desirable turf. Monument® herbicide is a great choice for follow-up applications and has been shown to further enhance bermudagrass or zoysiagrass regrowth by eliminating these sources of competition.
